Hello
For Min days between activities constraint, there is a button for Modify multiple constraints at once
Is it possible to have a filter by Subject, teacher, ...
The most important filter is the nunmber of subactivities
For example an activities splitted into 2 have 3 days Min
an activities splitted into 3 should have 2 days Min
activities from Subject Gymnastics should have 2 days Min..etc
I wrote this in the TODO.
